i) Uses the more idiomatic Wrap and Wrapf methods for creating nested errors.
ii) Fixes some incorrect usages of fmt.Errorf where the error messages don't have any formatting directives.
iii) Does away with the use of fmt package for errors in favour of pkg/errors

* promparse: sort all labels when parsing
Some label names might start with an uppercase letter in which case it
needs to come before __name__. Without this it means that we are not
maintaining the same invariant that all label names should be sorted in
such cases.
Amend the tests to check this problem automatically. Without the change
the tests do not pass.

This is based on the existing parser, and has slightly better
performance (few %) than it.

Pass content type down to text parser.
Add layer of indirection in front of text parser,
and rename to avoid future clashes.

To make local debuging with `go run` easyer moved all files into a
dedicate package `runtime`.
This allows running prometheus just by using `go run main.go` instead of
passing mani files like `go run main.go limits_default.go ...`

Extends the parser to allow retrieving metadata.
The lexer now yields proper tokens that are fed into a hand-written
parser on top.

The semantics of honor_labels are that if a target exposes
and empty label it will override the target labels. This PR
fixes that by once again distinguishing between empty labels
and missing labels in this one use case.
Beyond that empty labels should be pruned and not added to storage,
which this also fixes.
Fixes#3841
Instead, just make the anchoring part of the internal regex. This helps because
some users will want to read back the `Value` field and expect it to be the
same as the input value (e.g. some tests in Cortex), or use the value in
another context which is already expected to add its own anchoring, leading to
superfluous double anchoring (such as when we translate matchers into remote
read request matchers).
